The only solution to these intractable environmental impacts is the dramatic reduction, or complete elimination, of air travel. It might be hard to imagine life without the plane, but the idea is not as crazy as it sounds.

Here are nine common objections to grounding planes, and our counterpoints:

1. There are no fast, cheap and clean transport alternatives to the plane.

So we build them. We construct a national high-speed rail network and more efficient intercity, rural and urban transport systems. These projects would involve Australian steel, thousands of new jobs and large-scale regional planning and infrastructure development.

The continual development of communications technologies, including fast internet and virtual reality, will make much business travel redundant. Investing in virtual technologies and forcing the political and corporate elite to use other transport modes would hasten political support for, and investment in, the development of transport alternatives.

2. What about the economic value of tourism?

If we abandoned all tourist flights, the economy would be A$14.4 billion better off. International visitors spent A$38.1 billion in Australia in 2015-16. But, Australians travelling overseas spent far more – A$52.4 billion – in the same period.

International tourism, both in and outbound, would continue under a no–aviation scenario. As an island nation we will become reliant on ships. Travel by cruise ship is already booming. While cruise ships are currently highly polluting, their conversion to non-fossil-fuel energy, in contrast to the plane, is more achievable.

3. What about our education export industry?

Transnational education, teaching of students by Australian university offshore programs and via online distance education, is already significant, accounting for 30.2% of all higher education international students in 2015. We would invest more heavily in these educational platforms and technologies.

4. What about the jobs in the aviation industry?

Technological replacement and offshoring have decimated full-time jobs in Australia’s aviation industry. The employment generated by growth in domestic tourism and the construction of high-speed rail, ships and other transport alternatives would more than compensate.

5. What about the needs of farmers and hospitality industries who rely on backpackers?

We would still have a backpacker labour force under conditions of “slow tourism” that uses alternatives to cars and planes. Particularly for longer-stay tourism, arrival and departures by boat would be a small component of a trip.

We could also start using our own population for these jobs by paying higher wages. This might also reduce unemployment and dependency on social welfare and raise additional tax revenue. In the longer term we would transition to agriculture and hospitality industries that are not reliant on exploited and underpaid holiday-workers.

6. What about medical, military and rescue flights?

We need to keep essential flights for medical, rescue and firefighting purposes, and some military capacity. For essential flights, mitigation strategies like offsets may work as emissions would be low in aggregate.

8. Prohibition never works!

Banning things like alcohol has proven historically difficult, even in Canberra. But no-fly zones are easier to enforce – you couldn’t smuggle an A380 into the country and fly it around without anyone noticing.

9. It’s too radical a change – it would cause chaos!

Arguably, the controllable outcomes of grounding aircraft will be far less severe than the chaos of uncontrolled global climate change. A transformed, low-emissions transportation system can be planned for and, while there will be significant readjustment, life will go on.

A “business as usual” climate change scenario will unleash destruction unparalleled in human history, including the genuine threat of species extinction.

As an island nation we are more dependent than most on the aeroplane. Rather than giving us special dispensation, this puts us in a position to be world leaders in sustainable transport. Our proposal to ground planes and dramatically reduce emissions would need tremendous action in terms of civic will, and a state apparatus politically capable of taking radical action.
